This genuine Sterilight QS-330 UV quartz sleeve is the standard replacement for Sterilight S2Q and SSM-17 UV disinfection units. It comes complete with two replacement O-rings.
The transparent tube will last between 3-5 years naturally and that will be dependent on water quality and maintenance of your UV unit. It is advised that when you are due to change your UV lamp, you drain the system down and have a look at your UV quartz sleeve. Whilst out, any build-up on the outside can be removed with a scouring pad and if very stuck, the addition of an alkaline based cleaner. This will make the newly installed UV disinfection lamp more effective and help your UV quartz sleeve to remain unsoiled.
The UV quartz sleeves are fragile and while the glass can be touched, they should be handled with care. The biggest cause of breakages in relation to the UV quartz sleeves are from clients removing and reinserting them on an angle, they will freely break if put under any tension.
The UV quartz sleeve is a single replacement piece for a Sterilight QS330 UV unit. The picture shows both ends to show they are the same and that you can’t put them in the wrong way around.
